25 r .1 provide a book cover protector constructed of a sheet ofinexpensive material formed naeaaaa I i To all cvhom it may concern:

Be it known that I, Fmnonror-i O'r'ro' ZIM- MnRnAncKnL, a subject of the German Emperor, residing at New York, in the county'of New York and- State of New York,,hav,e invented certain new and useful Improvements in Book-Cover Protectors, of which'the following is a specification,

. y invention relates to book cover pro tectors.

, The primary objectof my invention to provide a book covenproteotor capable of detachable disposition on a book to protect the same against dirt, dust, or the llke, which .is simple innconstruction, cheap to 1 manufacture, and quickly andeasily secured onabook; I

Another object of my invention is to provide abook cover protector of the above described class which is capable of it use v in connection with books, of varying sizes,

means beingassociated therewith for :embracing the cover of 'a book to, prevent casual displacement of; the cover protector. A still further object of my invention is to combination, and arrangement of parts as hereinafter set forth in the specification'and illustrated in the accompanying drawings, inwhich---,- a a 1 Figure 1 is a'planviewof my improved book cover partly in section, showing the same applied to a book. up a a I @Fig. 2 is :a fragmentary plan View of the blank from whichmy improved book cover Fig, 3 is a transverse sectional view of the book cover protector taken on the line 33 of Fig. 1, and looking in the direction of the arrow.

'0 e form of my invention is illustrated L 6 5 as light paper, cardboard or the like, ispro vided and has arranged thereon creases, in this instance, three in number, the blank sheet of material being indicated bythenu meral 1 and thecreases by the numeralf2. The creases 2 are disposed substantially ine termediate the length of the blank and same isfreversely folded on said creasesito provide a pair. of spaced portions3 and 45 for a purpose which will hereinafter appear. The blank 1 isprovidedonrits longitudinal marginal edges with tongues 5, one

only being shown in Fig. 2, acrease G being provided adjacent the point at which the tongue joins the blank 1 in order to fa'cili tate folding of the same in the mannerhereinafter set forth.. The several lateralmarginal edges of the blank 1 arefolded, preferably three times upon themselves, suitable creases 7, 8 .and 9 being provided for this purpose, portions 10, 11, and 12 ofthe blank,

1 being foldable as illustrated in Fig. .3 to

provide a pocket 13 fora purpose Whichwill hereinafter be set forth, it being notedthat the portion 10 is first folded upon the crease 7 the portion 11 being in turn folded upon the: crease 8 reversely to the portion 10 and in parallelism thereto, the tongue 5, of

whichthere are two in the completed-article, being receivable between the r portions; 10, and 11, The portion 12 isnow'bentgbeneath the blank .1, a suitable adhesive material,

such as mucilage or the like is provided for permanently securing the tongues and portions 10, 11 and 12 in the manner shown in of one cover of the book designated 14 in Fig. 1. Additional means is provided for engagement with a book cover, this means i said portion 22 having two parallel portions 1 strap 15 in position.

comprising a strap 15, the opposite extremities 16 of which are receivable between the portions 3 and 4t, folded as hereinbefore set forth, the manner in which the extremities 16 are receivable between the folds 3 and 4 being shown to advantage in Fig. 3.

In disposing the book in position, one side "of the cover of the book is receivable under the strap 15, this cover being designated 17 in Fig. 1, the 'leaves'of the bookbeing designated 18. The other side of the cover, namely 14', is receivable in the pocket 13. It will thus be seen that the leaves of the book form an abutment against which the strap 15 engages and movement of the protector relative to'the book cover is practically impossible in this direction. In order to prevent casual displacement of the cover protector, the free marginal edges of the cover 14 are receivable in the pocket 13 in themanner hereinbefore set forth, and it will be noted that movement in any direction ofthe protector is practically impossible withotintentional removal of the cover protector.

In Figs. 5, 6, 7, and 8, I have'illustrated a modified form of my invention. In this form of my invention I provide a blank 19, said blank being folded on the creases 20 and 21 to provide transversely extending folded portions 22 and 23, respectively, the

24 and 25 between which are receivable the opposite extremities 27 of a retaining strap or band 26, substantially identical to the 0011- struction shown in Fig. 3 for retaining the The object of the folded portion 23 is to provide a clamping or retaining abutment and its advantage will readily become apparent hereinafter.

Afurther retaining band 28 isprovided, the opposite extremities 29 thereof being bent into parallelism with the main portion of the strap.2 8 and engageable between the portions of the blank 19 where the same is rever'sely folded as indicated at the point 30. The blank 19 is additionally creased at the point Moo-extensive with the outer marginal, edge of the folded portion 23 for a purpose which will hereinafter become apparent. I p i In applying this form of my cover to a book the back of the book is receivable between abutments 22 and 23, one-half cover of tlie book being-first inserted beneath the strap 26. The other half cover of the book is now receivable beneath the strap 28 and assuming that the book is of a thickness coextensive with that of the portion of the blank between the abutments 22 and 23, the protector willbe effectively retained on the book. Should the book be of a greater thickness than the distance between the abutnients 22 and 23, the abutment 23 may be folded into parallelism with the blank 19 and the cover protector folded on the crease 31. It has been found practicable, however, to manufacture these covers in different sizes to be employed with the size of book best adapted to the same and provision of the abutments 22 and 23 affords gripping and retaining means, being assisted by retaining straps 26 and 28. I desire to lay particular stress upon the manner in which the retaining straps of both forms of my invention are associated with the book cover protector, as well as the construction embodied, the peculiar manner in which the same is applied to a book not necessarily effecting the patentability of the various forms of my invention. Further attention is directed to the gripping and retaining abutments 22 and 23. It is, of course, to be understood that the straps 26 and 28, folded portions 2 1- and 25, the abutment 23, and the folded portion 30 are to be all secured with some adhesive material, such as mueilage or the like.

It is desired that it be understood that while I have shown my invention applied and used as a book cover protector,.it will be readily understood that the same might be illustrated for retaining photographs, postal cards and the like, this being the case particularly in the formof my invention illustrated in Figs. 1 to 4.

While I have shown and described my invention as possessing a peculiar form and construction, it is desired that it be understood that I may make such changes in the details thereof that do not depart from the spirit and scope of the invention as claimed.

*Having thus described my invention, what I claim and desire to secure by Letters Patent is: V

1. A book cover protector, including a body portion, said body portion being folded upon itself intermediate of its ends to provide an abutment for engagement with one side of a book binding, means included in the folded portion adapted to encircle the book cover adjacent to the bindingwhereby the protector is retained on the book cover, and pockets arranged upon the lateral marginal edges of the body portion of the protector for receiving the ends of the book cover.
